Turn the bar over
–
every time you sharpen the chain
and every time you replace the
chain – this helps avoid one-sided
wear, especially at the nose and
underside of the bar.
:
Regularly clean
the oil inlet hole
(1)
,
the oilway
(2)
and
the bar groove
(3)
.
:
Measure groove depth –
with scale on filing gauge* – in area
used most for cutting.
*
see “Guide to Using this Manual”
If groove depth is less than specified:
:
Replace the guide bar.
The drive link tangs will otherwise
scrape along the bottom of the groove
–
the cutters and tie straps will not ride on
the bar rails.
Dirty air filters reduce engine power,
increase fuel consumption and make
starting more difficult.
If there is a noticeable loss of
engine power
:
Move the Master Control lever (
1
)
to the normal run position.
:
Loosen knob (
2
) in direction of
arrow.
:
Remove the carburetor box
cover (
3
).
:
Clean away loose dirt from around
the filter.
